Abstract
Section titled āAbstractāThe local electrochemistry down to nanometer scale based on scanning probe technique with agarose as solid electrolyte will be presented. Boron-doped diamond conductive atomic force microscopy (BDD C-AFM) tip served as a working electrode which was brought into the surface of agarose gel electrolyte, forming the small electroactive area corresponding to nanoelectrode under the feedback by the current in a modified scanning ionic conductance microscopy mode along with a simple home-built Matlab software. Cyclic voltammograms show the controlled nanoelectrode predicted by COMSOL simulation. Moreover, this nanoelectrode enables the simultaneous imaging of both the topography and electrochemical activity of a polymeric microparticle embedded in a hydrogel, which may pave the new way to investigate the single entity electrochemistry of particles.
